Abstract: IEEE 802.1Q and Enhanced Transmission Selection provide only eight different traffic classes that may be used to control bandwidth in a particular physical connection (or link). Instead of relying only on these eight traffic classes to manage bandwidth, the embodiments discussed herein disclose using an Enhanced Transmission Selection scheduler that permits a network device to set the bandwidth for an individual virtual LAN. Allocating bandwidth in a port based on a virtual LAN ID permits a network device to allocate bandwidth to, e.g., millions of unique virtual LANs. Thus, this technique may increase the granular control of the network fabric and its performance.

Abstract: A method and system for a card-based game with simulates a traditional keno game through the use of a specially designed deck of playing cards. The system includes a computer, a scanner, a specialty card shoe, and the specially designed deck of cards. The method includes first shuffling the deck of cards by the specialty card shoe. Next, a card is drawn from the deck of cards and scanned, thus extracting a unique number that is associated with a spot on a traditional Keno card. The unique number is then associated and indicated to a spot on a simulated Keno card by the computer. This process is repeated for twenty iteration to compile winning numbers. The winning numbers are then compared against guessed spots associated with a user account to identify a set of matching spots. A primary payout transaction is managed based on the set of matching spots.
